У меня есть версия сообщества Alfresco, версия 5.2, с реализованным пользовательским рабочим процессом. Таков сценарий:

пользователь загружает документ в платформу и выбирает другого пользователя в качестве автора документа. Затем он запускает этот рабочий процесс с пользовательской логикой, как если бы его начал автор документа.

Я добился этого, переназначив инициатор рабочего процесса с помощью прослушивателя выполнения, сразу после запуска ScriptExecutionListener, но я получил всплывающее сообщение об ошибке, ничего не регистрируется в консоли или браузере.

Вот мое определение рабочего процесса

What am I missing?

why if I start the workflow within the API instead of using the default form processor the workflow is started and the initiator switched correctly?

I also posted the question on Alfresco forum, original link

Thanks
